Overtone Slider & Other Teaching Material
The Overtone Slider
A handy scheme for singing teachers, music teachers and composers.
The overtone slider is a handy scheme that displays precisely where the overtones are located in singing. The basic sheet with the piano shows the entire range of musically used tones. It indicates the ranges of the voice registers, the vocal formants and the double formants (for overtone singing).
The scheme is used together with the harmonic series. You immediately see which overtones are produced by the respective fundamental, how they interact with the formants in normal singing or speech, and which of them can be used for overtone singing. Composers can identify which singing tones can be used to produce certain overtones.
With the help of the scheme, the complete dependence of our resonance system (vocal tract) on the location of the overtones can be understood.
Tip: Do not adjust the margins when printing! This is because the overtone series must be printed in the same scaleg so that it fits exactly on the overtone slider.
